They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials.
In the physical sciences, subatomic particles are particles that are smaller than atoms.

Physical object

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.
Examples of models of physical bodies include, but are not limited to a particle, several interacting smaller bodies (particles or other), and continuous media.

They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Another type, microscopic particles usually refers to particles of sizes ranging from atoms to molecules, such as carbon dioxide, nanoparticles, and colloidal particles.
In the kinetic theory of gases, the term molecule is often used for any gaseous particle regardless of its composition.

Granular material

They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials.
A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide).

Point particle

point chargepoint massparticle
They gradually strip the baseball of most of its properties, by first idealizing it as a rigid smooth sphere, then by neglecting rotation, buoyancy and friction, ultimately reducing the problem to the ballistics of a classical point particle. These are usually abstracted as point-like particles, even though they have volumes, shapes, structures, etc. Examples of macroscopic particles would include powder, dust, sand, pieces of debris during a car accident, or even objects as big as the stars of a galaxy.
A point particle (ideal particle or point-like particle, often spelled pointlike particle) is an idealization of particles heavily used in physics.

Dust is made of fine particles of solid matter.

Particle accelerator

These would include particles such as the constituents of atoms – protons, neutrons, and electrons – as well as other types of particles which can only be produced in particle accelerators or cosmic rays.
A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams.

Particle physics

These particles are studied in particle physics.
Although the word particle can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behaviour.

Chemistry

These particles are studied in chemistry, as well as atomic and molecular physics.
In chemistry, matter is defined as anything that has rest mass and volume (it takes up space) and is made up of particles.

Quantum mechanics

quantum physicsquantum mechanicalquantum theory
Because of their extremely small size, the study of microscopic and subatomic particles fall in the realm of quantum mechanics.
Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values (quantization), objects have characteristics of both particles and waves (wave-particle duality), and there are limits to the precision with which quantities can be measured (the uncertainty principle).

Wave–particle duality

They will exhibit phenomena demonstrated in the particle in a box model, including wave–particle duality, and whether particles can be considered distinct or identical is an important question in many situations.
Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave.

Identical particles

They will exhibit phenomena demonstrated in the particle in a box model, including wave–particle duality, and whether particles can be considered distinct or identical is an important question in many situations.
Identical particles, also called indistinguishable or indiscernible particles, are particles that cannot be distinguished from one another, even in principle.

Mass

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.
A tachyonic field, or simply tachyon, is a quantum field with an imaginary mass. Although tachyons (particles that move faster than light) are a purely hypothetical concept not generally believed to exist, fields with imaginary mass have come to play an important role in modern physics and are discussed in popular books on physics.

Another type, microscopic particles usually refers to particles of sizes ranging from atoms to molecules, such as carbon dioxide, nanoparticles, and colloidal particles.
Atoms (complete with bound electrons) became to dominate over charged particles 380,000 years after the Big Bang—an epoch called recombination, when the expanding Universe cooled enough to allow electrons to become attached to nuclei.

Energy level

In general, a particle decays from a high-energy state to a lower-energy state by emitting some form of radiation, such as the emission of photons.
A quantum mechanical system or particle that is bound—that is, confined spatially—can only take on certain discrete values of energy, called energy levels.

Radiation

In general, a particle decays from a high-energy state to a lower-energy state by emitting some form of radiation, such as the emission of photons.
Like all elementary particles, photons are currently best explained by quantum mechanics and exhibit wave–particle duality, exhibiting properties of both waves and particles.

However, the noun 'particulate' is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation.
Subtypes of atmospheric particles include suspended particulate matter (SPM), thoracic and respirable particles, inhalable coarse particles, which are coarse particles with a diameter between 2.5 and 10 micrometers (μm) (PM 10 ), fine particles with a diameter of 2.5 μm or less (PM 2.5 ), ultrafine particles, and soot.

Colloid

Another type, microscopic particles usually refers to particles of sizes ranging from atoms to molecules, such as carbon dioxide, nanoparticles, and colloidal particles.
In soil science, the colloidal fraction in soils consists of tiny clay and humus particles that are less than 1ɥm in diameter and carry either positive and/or negative electrostatic charges that vary depending on the chemical conditions of the soil sample, i.e. soil pH.

According to our current understanding of the world, only a very small number of these exist, such as leptons, quarks, and gluons.
